Embodiment Construction

[0007] A method and device for positioning a molding die mandrel of the present invention will be further described below in conjunction with the accompanying drawings of examples.

[0008] A molding die mandrel positioning method and device of the present invention are composed of an umbrella cavity module 1, a mandrel 2, a thimble 3, a positioning fork 4, a mold frame 5, a tie rod 6, a roller 7, a slider 8, and a vertical tie rod 9; The specific embodiment of the present invention: pull the tie rod 6, the slider 8 moves, the roller 7 rises in the chute of the slider 8, the positioning fork 4 and the thimble 3 move upward through the vertical tie rod 9, and the thimble 3 supports the mandrel 2 , the positioning fork 4 blocks the mandrel 2 and cannot move horizontally. Because glue is higher than core rod 2 when molding, so the upper mold can not need thimble, core rod 2 can be positioned like this. When pushing the tie rod 6, the action is reversed, and the arc surface of th...

Abstract

The invention discloses a mould pressing die core rod positioning method and a device. The device is composed of an umbrella-cavity module 1, a core rod 2, a thimble 3, a positioning fork 4, a frame 5, a tie rod 6, a roller 7, a slide block 8 and a vertical draw bar 9, wherein the umbrella-cavity module 1 is arranged in the frame 5, the tie rod 6 is connected with the slide block 8, and the roller 7 is arranged in the chute of the slide block 8; the roller 7 rises to push the positioning fork 4 by the vertical draw bar 9; the thimble 3 moves upwards and supports the core rod 2; and the positioning fork 4 prevents the core rod 2 from horizontally moving. The invention adopts a die combination positioning mechanism, has small mould pressing technology investment and has favorable market space.

Description

technical field [0001] The invention relates to a molding die mandrel positioning method and device for a composite insulator, and belongs to the technical field of power transmission component manufacturing. Background technique [0002] The molding process is currently the most commonly used production process for low-voltage (voltage level below 110kV) composite insulators, with high production efficiency and low equipment and mold costs. However, the most popular ones for high-voltage products are the extrusion and parachute-through process and the injection process. However, the equipment and molds used in the injection process are very expensive, which hinders the promotion of this process. The investment in the molding process is small. Japan, Italy and other countries have successively done molding tests of high-voltage composite insulators, but they are not very successful. The main failure is that the mold has no positioning mechanism, resulting in too much eccen...
